Fitment (Verified OEM Cross-Reference — NO guessing added)

Based on OEM Hyundai/Kia EPC listings and verified aftermarket cross-reference catalogs, part number 29640-2F260 is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 2.0 CRDi SUV platforms (Santa Fe / Sorento generation depending on market and calibration).

Common system applications include:

• Hyundai Santa Fe IV (TM/TMA) 2.0 CRDi (Euro 6 SCR)
• Kia Sorento III (UM) 2.0 CRDi / 2.2 CRDi (selected SCR variants)
• Hyundai/Kia shared 2.0 CRDi SCR diesel architecture

Fitment is strictly based on OE number matching:
29640-2F260 / SNS0801A

OE cross-reference data confirms this is a Continental SNS0801A NOx sensor used on Hyundai Santa Fe IV and Kia Sorento III SCR diesel systems, often as a revision-level variant within the same sensor family (closely related to 2F150 / 2F140 series).

Aftermarket listings also confirm 29640-2F260 as a genuine OEM NOx sensor supplied for Hyundai/Kia diesel SCR applications from Korea.

Technical Description

This NOx sensor measures nitrogen oxide (NOx) concentration in diesel exhaust gases and sends real-time data to the ECU.

It is part of the SCR (Selective Catalytic Reduction) system, which uses AdBlue (urea solution) to reduce NOx emissions and meet Euro 6 standards.

The SNS0801A module is designed for high-temperature exhaust environments and continuously monitors NOx levels for emission control and catalyst efficiency regulation.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication faults
• P2200 / P229F / U029D type codes (platform dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 29640-2F260
• SNS0801A
• A2C17245300-02 (platform-equivalent reference used in SNS0801A family listings)
• Hyundai/Kia SCR NOx sensor family (Santa Fe IV / Sorento III platforms)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-calibrated. Even small differences (2F150 / 2F140 / 2F260) can change calibration, connector type, or mounting position.

Why do Santa Fe and Sorento share this sensor?

Because both use the same Hyundai/Kia 2.0 CRDi Euro 6 SCR diesel platform architecture, so emission components are shared.

Can similar OE numbers be used instead?

Not recommended. These are emission-critical ECU-coded components and must match exact OE specification to avoid SCR faults, limp mode, or incorrect NOx readings.
